It is no different than a car with a sunroof. My '78 New Yorker St Regis Coupe and my '05 Buick Park Avenue both with sunroofs have two drain tubes that go through the front pillars. Then can get plugged with the bacteria over time of water and must be cleaned out or find water on your front seat. The difference between this and adding them to the rails of a convertible is having access and remembering to occasionally maintain them.
